WafW00f - A firewall scanner
WafW00f is a web application firewall (WAF) fingerprinting tool that sends requests and analyses responses to determine if a security solution is in place.
WAFW00F does the following:
- Sends a normal HTTP request and analyses the response; this identifies a number of WAF solutions.
- If that is not successful, it sends a number of (potentially malicious) HTTP requests and uses simple logic to deduce which WAF it is.
- If that is also not successful, it analyses the responses previously returned and uses another simple algorithm to guess if a WAF or security solution is actively responding to our attacks.
Installation
We can install it with the following command:
Basic usage
wafw00f -v https://www.example.com
# -a: check all possible WAFs in place instead of stopping scanning at the first match.
# -i: read targets from an input file
# -p proxy the requests
